OracleRAC ACFS安装与卸载
目录
ACFS安装与卸载：
一、在RAC上手动安装ACFS/ADVM 模块的步骤如下：
1、验证内存中是否存在 ACFS/ADVM 模块：
2、用root用户重新安装ACFS/ADVM 模块：
3、ACFS/ADVM 模块是否已加载并存在于内存中：
4、成功安装ACFS/ADVM 模块后创建asm volume:
5、将asm volume格式化成文件系统：
1、用asmcmd volinfo-a确定卷路径
2、格式化成acfs文件系统
3、在RAC所有节点创建挂载点
6、在Oracle Registry中注册ACFS 文件系统：
7、将 ASM Volume (ADVM) 上挂载 ACFS 文件系统：
8、将ora.registry.acfs服务注册进集群：
二、在RAC上卸载/删除 ACFS/ADVM 模块的步骤如下：
1、卸载 ACFS 文件系统：
2、在Oracle Registry中取消注册ACFS 文件系统：
3、删除asm volume：
4、验证内存中存在 ACFS/ADVM 模块：
5、停止CRS或OHAS 服务:
6、从内存中卸载 ACFS/ADVM 模块：
7、再次验证内存中是否存在 ACFS/ADVM 模块：
8、 卸载安装的ACFS/ADVM模块：
9、启动crs或ohas服务:
10、查看集群资源状态：
11、移除ora.registry.acfs服务:
12、再次查看集群资源状态：
ACFS安装与卸载：
在配置acfs之前一定要先检查内存中是否存在 ACFS/ADVM 模块
否则创建asm volume会有如下报错：

一、在RAC上手动安装ACFS/ADVM 模块的步骤如下：

1、验证内存中是否存在 ACFS/ADVM 模块：

在下面的示例中不存在该模块：

2、用root用户重新安装ACFS/ADVM 模块：
